Safety operating procedures for crushers implemented by double-roller crusher manufacturers
) General provisions
Drivers of loaders and double-roller crushers must be trained to achieve three understandings (understand the structure, understand the performance, and understand the principles) ), four skills (knowing how to use, know how to maintain, know how to maintain, and know how to deal with faults). Only after passing the training examination and obtaining the certificate can you be allowed to work. Work closely with the working surface scraper conveyor driver and the transport lane belt conveyor driver, communicate with each other through unified signals, and start and stop in sequence. When large pieces of coal and gangue accumulate and overflow at the feed port of the crusher, the operation of the machine and surface scraper conveyor should be stopped. If there are large pieces of coal or gangue that cannot enter the crusher or if there are metal objects, the machine must be shut down for processing.
) Preparation before operation
Tools include wrenches, pliers, screwdrivers, hammers, shovels, etc. Prepare necessary spare parts: various short-circuit chains, chain rings, bolts, nuts, crusher insurance Pins, etc., as well as lubricating oil and turbine oil.
) Inspection and processing
The connecting parts of the motor, reducer, hydraulic coupling, machine head, tail and other parts must be complete, intact and tight. There should be no oil leakage or oil leakage in the shaft joints of the reducer and hydraulic device. The amount of oil should be appropriate and the signal must be sensitive and reliable. The machine is not allowed to be started without a signal. The spray sprinkler device must be in good condition. The power cables and operating wires must be hung neatly and without squeezing. The coal, gangue, debris and motor and reducer coal dust near the machine head must be cleaned and cleaned, scraping the conveyor machine head and transfer machine on the working surface. The overlapping of the tail of the machine must be suitable for the scraper chain plate. The scraper and the screws must be completely tightened. The traveling trolley of the transfer machine must be stable and reliable. When starting up the bridge part of the transfer machine, there should be no abnormal sound in the operation of each part. The scraper must be completely tightened. , Chains and connecting rings should be free of twisting, twisting, and bending deformation. The tunnel support at the crusher must be intact and firm. The safety protection net and protection device of the crusher must ensure that it does not deform or fail, and is safe and reliable. The tunnel support at the loader and crusher must be intact and firm.
) Operation and Precautions
Trial operation, close the magnetic starter handle, press the power button, click the button for two or three times to start, idle ~ the combined operation of the turnover loader and crusher, check that there is no abnormality, and issue Power on signal. During operation, the machinery and motor must have no vibration, the sound and humidity must be normal, the temperature of each bearing should not exceed ℃, and the motor temperature must not exceed the manufacturer's regulations.
In addition, the chain tension of the transfer machine must be consistent. Under full load, the chain tension is not allowed to exceed the length of two links, and there must be no chain jamming or chain skipping. After the fusible plug or fragile piece of the transfer joint is damaged, it must not be replaced with wood or other materials. Double-roller crusher | The protective net safety device of the crusher should be kept intact and should be checked frequently during the working process. If there is any damage, the machine should be stopped immediately for processing. The safety devices such as tail protection of the transfer aircraft must be kept intact.
